问题描述
我有一些带有一些字形的图形,但只希望显示某些字形的工具提示。目前有一种方法可以在Bokeh中实现这一点吗?
或者,有没有办法将两个数字打在一起?看起来这样可以让我完成我想要做的事情。

感谢Google Groups中的这个页面,我想出了如何这可以做到。
编辑2015-10-20 :看起来像谷歌组链接不不幸的是工作。这是来自Sarah Bird @bokehplot的消息。
编辑2017-01-18 :目前这会将多个悬停工具图标添加到工具栏。这可能会导致问题。 github上已经有一个问题。或者,在下面的答案中尝试@ tterry的解决方案。
基本上你需要(散景版本0.9.2):
示例:
import bokeh.models as bkm
import bokeh.plotting as bkp
source = bkm.ColumnDataSource(data = your_frame)
p = bkp.figure(tools ='添加你想要的工具,但没有悬停!')
g1 = bkm.Cross(x ='col1',y ='col2')
g1_r = p.add_glyph(source_or_glyph = source,glyph = g1)
g1_hover = bkm.HoverTool(renderers = [g1_r],
tooltips = [('x','@ col1'), y','@ col2')])
p.add_tools(g1_hover)
#现在重复上面的nex t套你想添加的字形。
#对于那些你不希望工具提示在悬停时显示的,只是不要
#为他们添加悬停工具!
另外,如果您需要为每个要添加的字形添加图例,请尝试使用 bokeh.plotting_helpers._update_legend()方法。 例如:
_update_legend(plot = p,legend_name ='data1',glyph_renderer = g1_r)
I have a figure with some glyphs, but only want tooltips to display for certain glyphs. Is there currently a way to accomplish this in Bokeh?
Alternatively, is there a way to plot two figures on top of each other? It seems like that would let me accomplish what I want to do.
Thanks to this page in Google Groups I figured out how this can be done.Link here
Edit 2015-10-20: looks like the google group link doesn't work anymore unfortunately. It was a message from Sarah Bird @bokehplot.
Edit 2017-01-18: Currently this would add multiple hover tool icons to the tool bar. This may cause problems. There is already an issue filed at github here. Alternatively, try @tterry's solution in the answer below.
Essentially you need to (bokeh version 0.9.2):
Example:
import bokeh.models as bkm import bokeh.plotting as bkp source = bkm.ColumnDataSource(data=your_frame) p = bkp.figure(tools='add the tools you want here, but no hover!') g1 = bkm.Cross(x='col1', y='col2') g1_r = p.add_glyph(source_or_glyph=source, glyph=g1) g1_hover = bkm.HoverTool(renderers=[g1_r], tooltips=[('x', '@col1'), ('y', '@col2')]) p.add_tools(g1_hover) # now repeat the above for the next sets of glyphs you want to add. # for those you don't want tooltips to show when hovering over, just don't # add hover tool for them!
Also if you need to add legend to each of the glyphs you are adding, try using bokeh.plotting_helpers._update_legend() method. github source Eg:
_update_legend(plot=p, legend_name='data1', glyph_renderer=g1_r)
这篇关于散景绘图:仅为某些字形启用工具提示的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
